Application September 29, 194 3,"S erial No. 504,321 Claims. 01. 77-63) work can be instantly released and permitted to fall to a collecting receptacle or other appointed place.

Another important object of the invention is to provide a work holding device of the character stated which is positive acting and substantiallyfool-proof in all respects.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a top plan view of the holder.

Figure 2 is a side elevational view.

Figure 3 is a transverse sectional view taken on line 3-3 of Figure 1.

Figure 4 is a top plan View of the supporting plate.

Figure 5 is a perspective view of the actuating lever.

Figure 6 is a perspective view of the jaws.

Figure 7 is a sectional view taken substantially on line I--I of Figure 1.

Figure 8 is a perspective view of the work rest member.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that numeral 5 denotes a supporting plate having deing a slot I I therein and each having a V-notched end portion I2, these end portions I2 being in opposed relation. 4

A depression I3 is provided in the plate 5, this cutting into the bottom of the channel 8, this depression having an arcuate wall I4 and a straight wall I 5, and in this operatesa work rest I6 (see Fig. 8), one end of which is rounded oif, as at I 'I, to ride the arcuate wall I4. Through the plate 5 from the bottom and opening through the depression I3 is a round opening I8 through which finished work can drop, and it is the function of the work rest l6 to support the work and prevent the same from falling through the opening untilthe work thereon has been completed.

Screws I9 aredisposed through the slots II in the jaws 9, II], it being preferable that the'jaw 9 beheld stationary as much as possible while the jaw I0 is left loose to be slid.

A lug 20 rises from one side of the plate 5 and has a threaded opening therethrough for receiving a feed screw 2| which is adapted to bear against the outer end of the jaw 9.

A pivot screw 22 is disposed through the opening 23 of the rest I6 and into an opening 24 in the plate 5. The work rest I6 has an anchor 25, and an anchor 26 rises from the plate 5, and between these anchors is a tension spring 21, normally serving to hold the free end of the rest I6 ,over the work dispensing opening I8 (see Fig. 1).

An elongated actuating lever 28 has a lug 29 thereon through whichv a screw 30 is disposed and adapted to engage the jaw I0.

v The plate 5 is provided with a second upstanding lug 3| through which a screw 32 is disposed and is located within the path of the foot 33 of a pivotal dog 34. Anchoring means 35, 36 on the dog 34 and plate 5, respectively, serve as attaching points for the ends of a tension spring 31, to hold the hook head 38 of the dog 34 engaged with a shoulder 39 on the adjacent end of the work rest I6.

It can now be seen that by pulling the lever- 28 to the dotted line position shown in Figure 1, work can be inserted between the jaws 9, I 0 after which, by holding the work and releasing the lever 28, the jaw It! will be forced against the work in order that the work be clamped between the jaws, and the rest I6 will be in a position shown in Figure 1, with the dog 34 engaging the shoulder 39 of the rest I6.

As soon as the cutting operation has been performed on the work, the lever 28 can be moved to the dotted line position shown in Figure 1, which will result in release of the jaw ID and movement of the work rest I6 to the left in Figure 1, thus releasing the work so that it will fall through the work dispensing opening I8 in the plate 5.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of th invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A work holding device comprising a base jaws on the base for holding work over the work.

dispensing opening, an operating member on the base for releasing one of the jaws, and actuating the work rest simultaneously.

2. A work holding device comprising a base having a work dispensing opening therein, a work rest swingable over the work dispensing opening, jaws ronathe base for holding work over the work dispensing opening, an operating member on the base for releasing one of the jaws, and

actuating the work rest simultaneously, said actuating member being provided with afrocleablepawl engageable with the work rest.

3. A work-holdingdevice comprising --a -'lu'irizontal supporting plate having means "to facilitate fastening the same to asuppnrttandgprovided with a raised portion having a vertical opening therethrough and formed in its upper surface withsaohannelinterseoting said opening opposed jaws .slidably secured :in said channel, means to adjust one jaw toward .or away ,trom the other jaw, a horizontally .swingable work rest ,pivoted on the isupzponting plate and .movable ion a ,plane below the ,jaws .to cover or uncover .said fopening, yieldable means acting toswing thework rest inza direction :to never said opening, a horizontally swingable lever ,pivoted .on the supporting plate and having .a member ,ior engaging and moving said other jaw towardsaid onejawahookedidog pivoted .on said lever .and sengageahle with the work west for moving theilatter to answer said opening when the lever is swung to release said other jaw.

:4. A work-holding device nomprising .a horizontal supportin p ate having means-to tacilitateta'stening of the same .to a support and proadded with -a raised portion having .a vertical @opening therethmugh iormed in its surface with a channel intersecting said opening, opposed jaws slidably secured in said channel, means to adjust one jaw toward or away from the other jaw, a horizontally. swingable work rest pivoted on the supporting plate and movable on a plane below the jaws to cover or uncover said opening, yieldable means acting to swing the work rest in a direction to cover said opening, a horizontally swingable lever 'pivoted on the supporting plate and having a member for engaging and moving said :other jaw toward :said zone jaw, a hooked dog pivoted on saidlever and engageable with the work rest for moving the latter to uncover said opening when the lever is swung to release "said other jaw, and an abutment in the path of said dog for releasing the latter from the work rest after the latter has uncovered said opening and said other jaw has been released.

5. .-A.-work-holding device comprising a horizontal supporting plate having means to facilitate fastening of the same to a support and pro- :vided with .a raised portion. having .a vertical opening .therethrough and iormed in its upper .suriace withachannel intersecting said opening, opposed jaws .slidably secured in .said channel, means to adjust one jaw toward or away irom the other jaw,-.a. horizontallytsw ngable work rest (pivoted ion .the .supportmg plate and movable on .a ,plane lbelow the jaws .to never .or .uncover .said opening, yieldable means acting to swing the .work rest .in .a direction .to cover .said opening, a horizontally .swingable lever ,pivnted -on the sup.- portingplate and having a member for engaging and moving said other jaw toward said one (jaw, ,a hacked .dogpivoted on .said lever and-engage- .ahle with ,the work rest for moving the latter to uncover said opening when the lever is swung to release .said other jaw, said member tor engaging and moving said other jaw embodying a screw adjustable transversely of the lever.
